For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:https://security.FreeBSD.org/>.

I.   Background

SQLite is an SQL database engine in a C library.  Programs that link the
SQLite library can have SQL database access without running a separate RDBMS
process.  The distribution comes with a standalone command-line access
program (sqlite3) that can be used to administer an SQLite database and which
serves as an example of how to use the SQLite library.

FreeBSD includes SQLite as a private library for base system usage that is
not generally exposed for third party packages to use.

II.  Problem Description

Multiple vulnerabilities have been published including improper input
validation (CVE-2020-11655), use after free (CVE-2020-11656, CVE-2020-13630),
integer overflow (CVE-2020-13434), null pointer dereference (CVE-2020-13435,
CVE-2020-13632), and namespace collision (CVE-2020-13631).

III. Impact

Malicious SQL statements could crash, hijack processes, or cause data
corruption.

IV.  Workaround

No workaround is available.  The FreeBSD security team is not aware of any
base system components that use SQLite in such a way as to expose these
vulnerabilities to untrusted or remote users, but is updating SQLite out of
an abundance of caution.

V.   Solution

Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.

Perform one of the following:

1) To update your vulnerable system via a binary patch:

Systems running a RELEASE version of FreeBSD on the i386 or amd64
platforms can be updated via the freebsd-update(8) utility:

# freebsd-update fetch
# freebsd-update install
# shutdown -r +10min "Rebooting for a security update"

2) To update your vulnerable system via a source code patch:

The following patches have been verified to apply to the applicable
FreeBSD release branches.

a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.

[FreeBSD 12.1]
# fetch https://security.FreeBSD.org/patches/SA-20:22/sqlite.12.1.patch
# fetch https://security.FreeBSD.org/patches/SA-20:22/sqlite.12.1.patch.asc
# gpg --verify sqlite.12.1.patch.asc

[FreeBSD 11.4]
# fetch https://security.FreeBSD.org/patches/SA-20:22/sqlite.11.4.patch
# fetch https://security.FreeBSD.org/patches/SA-20:22/sqlite.11.4.patch.asc
# gpg --verify sqlite.11.4.patch.asc

[FreeBSD 11.3]
# fetch https://security.FreeBSD.org/patches/SA-20:22/sqlite.11.3.patch
# fetch https://security.FreeBSD.org/patches/SA-20:22/sqlite.11.3.patch.asc
# gpg --verify sqlite.11.3.patch.asc

b) Apply the patch.  Execute the following commands as root:

# cd /usr/src
# patch < /path/to/patch

c) Recompile the operating system using buildworld and installworld as
described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>.

Restart all daemons that use the library, or reboot the system.
